From: Jagan Teki <hidden>
Date: 2018-05-18 09:46:36
Also in:
dri-devel, linux-arm-kernel, linux-clk, lkml
Subsystem:
drm driver for allwinner de2 and de3 engine, drm drivers, drm drivers and misc gpu patches, drm drivers for allwinner a10, the rest · Maintainers:

From: Jernej Skrabec <redacted> When TCON set up TCON TOP, it needs to know mixer index. Here we do that by setting engine ID to number provided in mixer index quirk.
